Abstract (en)
A device is provided for recording and/or reproducing information. It comprises a probe electrode (102), a recording medium (101) disposed opposite to the probe electrode (102) so that a tunnel current can flow when a voltage is applied therebetween and either one or both of (a) means (112) for applying a writing voltage between the probe electrode and the medium to record information thereon and (b) means (112) for applying a reading voltage between the probe electrode and the medium to detect information recorded thereon. The medium comprises organic molecules which have both a group containing only sigma electron levels and a group containing π electron levels. It may comprise a monomolecular film of an organic compound or a film built up from a plurality of monomolecular layers of an organic compound which may be, for example, a dye.
